I feel that in usage, lyrical is the 'soft jazz' that is always done to sad, angsty, nostalgic or sweet songs. In usage, 'contemporary' usually means 'modern jazz' or 'new jazz' that is done to more of a variety of music.
The greatest integer function of a real number x is represented by f(x) = [x] or |_x_|. For all real numbers x, the greatest integer function returns the largest integer less than or equal to x. In other words, the greatest integer function rounds down a real number to the nearest integer.
Use Euclid's Algorithm to find the Greatest Common Divisor (GCD) of two numbers. Let's say the two numbers you're using are 210 and 45. Here's how you use Euclid's Algorithm to find the GCD of both numbers: First, divide the first number by the second: 210/45 = 4 with the remainder of 30. This means that 210 = 4 x 45 + 30.
